Hi there! I understand you’re seeing unwanted items in your TPT cart that you didn’t add, and you can’t remove them, which is blocking you from buying the items you want. That definitely sounds like something we can work on fixing together.

To help me narrow down the issue, could you tell me a bit more? For example:
- Are you using the TPT website or the app on your Mac?
- Is this happening with specific items, or does it seem random?
- Have you tried any specific steps like refreshing the page, logging out and back in, or clearing your browser cache yet?

In the meantime, here are some steps that usually help resolve cart issues on TPT or similar platforms on a Mac with OS X 10.15.7:

1. Refresh your browser or app: Sometimes temporary glitches cause odd cart behavior. Restart your browser and log back in to TPT. If you’re using Safari, Chrome, or Firefox, try another browser to see if the cart behaves differently.

2. Clear browser cache and cookies: Leftover site data can interfere with proper cart function. On your Mac’s browser, go to settings or preferences, find privacy or history, then clear cache and cookies specifically for the Teachers Pay Teachers site.

3. Check for any “minimum purchase” requirements or set bundles: Some items might be linked in a way that forces a minimum purchase, so the cart doesn't let you remove them. If you see any notes or messages in the cart interface mentioning minimums or bundles, let me know.

4. Try removing items one at a time: On the cart page, hover or click on the item you want to remove and look for a small “X,” “Remove,” or trash bin icon. Sometimes the remove option appears only when the mouse is over the item.

5. Use an incognito/private browsing window: Open a private browsing session and log into your TPT account there. Adding the same items again may help isolate if browser extensions or cached data cause the problem.

If these don’t work, it could be a more specific glitch in the TPT app or website needing deeper investigation or a fix from their end. In that case, please let me know your experience with the above, and I can guide you on contacting TPT support or escalating further.

Does that sound good? I’m here to help you get this sorted.
